JULIUS HENRICI'I, OF PHILADELPHIA, PENNSYLVANIA.

BUTTON-TURNI NG MACHINE.

SPECIFICATION Application flied March 1.1901.

To tZZ whom it may concern: l

Be it known that I, JULIUS HENRICH, a subject of the Emperor of Germany, (but having declared myintention of becominga citizen of the United States of America,) residingin the city of Philadelphia, countyof Philadelphia, and State of Pennsylvania, have invented new and useful Improvements in Button- 'lurning Machines, of which thefollowing is a specification. v

Myinvention relates to machinery for Inaking pearl orl other buttons, and Amore particularly to such as is used for facingl the same; and the object thereof is to provideV a machine by which button-blanks are automatically fed from a feeding disk or band to the clutch mechanism in order to increase the capacity of the turning-machine and to reduce the cost of labor, as one attendant may easily operate two or even three such machines.

My invention consists of a button-turning machine having a rotatable clutch and an automatically-sliding tool-rest, a feed table, or band, and means for automatically transferring the button-blanks from the feed-,table to and into the chuck; and myinvention further Aconsists of the improvements hereinafter more fully described, and pointed out in the claims.

My invention will be more fully understood taken Ain connection with the accompanying drawings, forming part hereof, and .in whichj 4 Figure lis a plan of a lathe or button-tu rning machine embodying my improvements. Fig. 2 is a longitudinal section of the said machine, showing the chuck, the automatic feeder, the tool, and means for sharpening the same. Fig. 3 is a transverse section of the machine just in front of the feeder, lshowing the latter and its operating mechanism in elevation. Fig. 4 is a side view of a party of the feeder. Fig. 5 is a central longitudinal section of the spindle with chuck havingv a button-blank clamped therein and also showing the feeder in section and at its highest position. Fig. 6 is a perspective rear view of the feeder, showing also the means for operating the feeding-table. Fig.. 7 is a top view of the feeding-table for the button,- blanks and its operating mechanism, together withthe button-blank, transferring device.V

forming part of Letters Patent No. 711,723, dated October 21, 1902.l

Serial No. 49,477.. (No model.)l

Fig. 8 is a central longitudinal section of the spindle with chuck, showing the ejection of a finished button therefrom and the transferring device almost in position to insert a new button-blankiinto the chuck. Figs. 9 and l0 are views similar to Fig. 8, showing the different positions of the transferring device.

Referring now to the drawings for a further description, A is the base of the inachine, in which the main shaft B is jonrnaled.

This main shaft B is driven from a countershaft B by means of the belt b3 to operate the chuck C, feeder F, and tail-stock or toolrest T by means of cams4 which will be hereinafter more fully described. From the shaft B the sleeve c and chuck-spindle c2are driven by the pulleys b2 and belts b3,and the countershaft B is driven from anysuitable power by means of the fast and loose pulleys b.

The chuck C for holding the button-blank is made in any desiredV Inanner,but preference is given to the construction as shown in Fig. l, in which the chuck-head is split land provided with a conical shoulder normally seated in the enlarged opening of the sleeve c'. The chuck C is provided with a spindle c2, which is keyed or otherwise held to the sleeve c', so that the spindle c2 may be moved longitudinally to cause the opening and closing of the jaw's of the chuck. In the sleeve c' is formed an enlarged opening c3, in which a spring c4 fornormally closing the chuck is chuck-spindle c2 and normally projects..

through the front end of the chuck by the action of a spiral spring e9, pressing with 'one end against the shoulder of the rod e8, which, however, is limited in its outward movement by the oifsetted aperture inthe spindle c2.v

VThetool t is carried on a sliding tail-stock T, mounted on a slide a of the base A and Is.. g

icc

moved longitudinally on the slide a by means of the vcam t2, .bearing on a roller` t3 of the tailstock T. A counterweight (not shown) suspended over a pulley by a chain insures contact of the roller t3 with the cam t2, so that the movements of the tail-stock are regulated entirely by the cam t2. This cam t2 and the cam c7 for actuating the chuck C operate in such a way that when va button-blank is being iu- ,L serted into the rotating chuck C the tool is farthest away from the same, and as soon as the chuck closes the toolzf moves quickly against the rotating button-blank to face or turn the same. The tool-holder or tail-stock may be 0f any desired construction; but preference is` given to that shown in Figs. l and 2, in which a vertical adjustable sleeve i514 carries the Y- shaped tool-holder 5, .on each of the two arms t6 of which a tool is clamped, so that while l one tool t is in operation the other may bei sharpened or replaced without stopping thef` machine. The tool-holder t5 is held in the sleeve 14 by means of a suitable spring t7 and is prevented from turning by the lugs s e-n- Q gaging slots t9 in the sleeve 14 'and projec- 5 tion 1 of the tail-stock T. In order to re-l. verse the tools, itis necessary to only thmw the spring or spring-catch t7 back and 'lift' the tool-holder t5 sufficiently to disengage the lugs 158 from the slots lt" and turn the said toolholder t5 one -hundred and eighty ldegrecs. The raising and lowering ofthe toolholder t5, which is necessary to set the tool' into proper relation with the chuck C, is effected by the nutt11,insertedbetween cheeks of the tail-stock T and lmeshing with the threads of ythe sleeve 14, so that by turning the nut t11in one direction thesleeve 1514 and tool-holder t5 will be moved downward and when turned inthe opposite :direction thesleevet11 and tooill holder t5 will be moved upward. To properly set the tool t Anot in use, a gage g--is provided, consisting-of an arm g', pivot-ally mounted cn l a post g2 of the machine-bed A,.and to sharpen 2 the tool not in use a grindstone or emerywheel g3 is journaled onaswingingar-m g4and driven from the counter-shaft B 'by means of l belts g5 gs and pulleys g7, g8, yand Q9, as y,mayf be readilyseenffrom Figs. land 2. In orde-r to feed the button-blanks auto-m'ati ically -in-.to the chuck (La rotarydsk D is arran-ged above the chuck C, and a device ori feeder F is provided in fronit ot' the chuck to 'j transfer the button-bl-ank .fr from-the disk D to the chuckpC, kand this is accomplished in the following man-ner: Above thek journal a for the chuck-spindle sleeve c' is provided a circular table D', supported by the posts d and having a central sleeve or 'bearing d f. `formed thereon. The disk D is provided with l 'apertures d2 the size of the button-blanks a: and is rotated bymeans of a ratchet-wheel` cl3, secured to a stem dief the disk D. This l ratchet-wheel d3 has 4as many teeth as there are Aapertures d2, so that when the wheel is` moved the space of one tooth by means of a `pa-wl d5 an aperture d2 registers with an opening d6 of the table D and permits a buttonblank w to fall into the chute (Z7, from which it is transferred to the chuck O. It is important to present the best or solid side of a button-blank to the tool, and by arranging the devices as just described this result will be secured, as the attendant in charge will place the side of the blank to be faced uppermost, so that when the latter entersithe chute the face of the button-blank is outwardly.

At the front of the chuck C and surrounding the same is a face-plate f, secured to the `machine-base A by means of a stud f and set-screwfz in such a manner that the chuck C when open is flush with the face of the said plate f. At a distance from the center of the face-plate f, Fig. 3, is provided a vertical `sliding bar je, recel-vingvreciprocating motion from the mai-n lshaft B .of lthe lmachine by means lof an eccentric f4, ecceu-tricvstrap f5, and |link f6, `and this eccentric is fso `fset in relation to the cams clandt'lthat-whenthe tool t travels away from vthe ch and ythe latter vopens the sliding bar fs 'is lowered, Iand when the chuck closes and the tco'l advances toward -the chuck the 'bar f3 iis raised.

'Rig-idly attached to the bar f3 is a crossbar f8, provided with :an aperture in 'which a plug fg, secured to Van auxil'i'aryhar f1, is-attached. This auxiliary bar f10 is "held lslidingly-to the cross-bar f'by mea-ns'oftfhestudscrews f1.1 and is lheld outwardilylth-rouggh the flat springs f12, bearing with their respective ends-against the four pins f13, secured in the cross-bar f8.

vTo the freeend of the cross-'barj'8 is secu red a guideA f14, carrying 4a -ii-ex'ble cam f 'to operate a lever f1 and plug f17. The latter is arranged in the plate f just below-the chute dito, first,prevent a button-blank vin the same from'falling through-the opening when the cross-bar f8 is in its lower position, and, secondly, to force ya button-blank against the action of the flat springs f12 into the cpan-ing of the `cross-bar f8, as shown in Fig. 5. The lever f1 is pinned to the ipl-ug f at f18, and a springf19 normally presses against the lever f16, so that the `outer end of of the plug f17 is 'ush with the face of the plate f.

In order to rotate the disk 'D-by means of the ratchet-wheel d3, Aa c am d8 is fastened to the rear of the sliding bar f3, vwhich slides up and down therewith and yoscillates a vlever dg, to which the pawl d5 is hinged, Figs. il, 6, to '8. When the cross-bar f8 is vopposite the chuck C, Fig. 10, it is necessary to force Athe button-blank out of the cross-'bar `and y'in-to the chuck C Iand 'against the yaction yof the spring o9 of therod e8 in the-chuck C, and this `is accomplished by the rods r', muuu-ted lin a cross-bar t" and theface-plate f,a\nd,are connected by a bar i2. In each of the two rods i is mounted a pin 113, and between this -and the face-plate f 'is inserted a spring 4, so'that the rectangular projections fis, one at each rod c', are normally pressed against the face of the plate f. Both of these rectangular pro- IOO ITO

. jections 5 are moved away from the face of the plate f in order to let the auxiliary bar flo pass between by the lever 6, pivoted to the base A of the machine and bearing with its upper end against the bar 2 and with its lower end against a cam 7 on the shaft B of the machine. This cam 7 is of sucha shape and set in relative position with the cams c7, t2, and eccentric f4.as that the projections-7l5 are moved outwardly before the auxiliary barf10 reaches its lowest position, when they will be relieved of the action of the cam 7 and be forced by the springs 4 to press the 'auxiliary bar flo, with plug fg, toward the open chuck C, forcing the button-blank fr.

into the same and following the chuck C until it is closed, after which the cross-bar f8 moves upward and the projections 5 under the influence of the springs 4 return to their normal position against the face-plate f.

The actions of the feeding devices just described are as follows: The chuck C is constantly rotating at a speed of, say, seven hundred revolutions per minute, and the speed of the main shaft Bis about eighteen revolutions per minute, so that about eighteen buttons may be faced in one minute on one machine, each facing requiring about forty revolutions of the blank. The button-blanks .r are placed by hand, with their face sides up, in the apertures of the disk D, which, as before stated, delivers one blank to the chute @Z7 whenever one button-blank is faced and re leased from the chuck C. When the tool t is in position, as shown in Fig. 2, one button-blank is in the chuck C, Fig. 5, being faced and one is in the aperture of the cross-bar f8 ready to be brought into the chuck C. The button in the chuck being finished, the tool t recedes, and the chuck C through the instrumentality of the cam c7 and lever c6 opens and the button is forced out of the chuck by means of the rod e8, Fig. 8'. In the meanwhile the crossbar j, with the auxiliary bar flo and holding the button-blank, is lowered by the cam f4, cam-leverf5, linkf, and sliding bar f3 until the center of the button-blank is in line with the center of the chuck C, which latter when open, Fig. 10, is flush with the face of the plate f. The rectangular projections, Fig. 8, having before been movedfrom the face of the plate f by the cam 7 and lever 6, the latter now gliding off the high section of the cam 7 permits the springs 4 to force the projections 5, Fig. 10, against the ends of the auxiliary bar flo and press the button-blank into the chuck C against the pressure of the spring cg of the rod o8. By the downward movement of the sliding bar]c3 the disk D is turned so as to feed another button-blank into the chute 17, Fig. l0, and this is held by the plugf17. In the upward movement of the sliding barf3 with cross-bar]e8 and springcam 7"15 the latter engages the end of the lever f'l and forces the same backward against the action of the spring f1 to withdraw the plug f, Fig. 9, and allow the button-blank to drop, so that it is between the two plugs f17 and fg, Fig. 9. The springf19 being stronger than the springs f12 on the auxiliary bar f1", the plug f presses the button-blank into the opening of the cross-bar f8, Fig. 5, so that by its next downward movement another blank is presented to and pressed into the chuck C. In the downward movement of the sliding bar f3, cross-bar f8, and the spring-cam f15 the latter passes the end of the lever f1@ without actuating the same, as may be seen from Figs. 6 and 7, while when the spring-cam f15 moves upward the point of the cam engages the lever f1 and forces the free end outward to actuate the plugf, as described.

It will be understood by those skilled in the art to which this invention pertains that modifications may be made in the construction and arrangements of the devices .for transferring button-blanks from a feeder to a constantlyrevolving chuck,r and I especially call attention to the fact that modications may be made without departing from the spirit of the invention as herein described.

Having thus described the nature and objects of my invention, what I claimy as new,

and desire to secure by Letters Patent, is
